Okay, now THIS is cool.
Using your Weber to make glass? Awesome. BUT…. if I can hit 2k in a grill, it means that I can not merely make glass, but also fire my own ceramics. All you need is to regulate the temperature curve so that you don’t shatter the stuff.
I love ceramics, and haven’t done any for years precisely b/c of lack of kiln access… so, quite cool.
